Application filed Inlay 31, 1918. Serial 2-10. 2373M.

To all whom it may, concern Be it known that I, .lonm F. GODFREY, a citizen of the United States, residing in the city of Elkhart, county of Elkhart, and

State of Indiana, have invented certain new and useful Improvements in Self-Dumping ilonveying-Buckets, of which the following is a specification.

This invention relates to improvements in self dumping buckets and especially to self dumping buckets used for conveying coal, and like materials, from one place to another. 1

An object of my invention is the production of a self dumping bucket provided with bottom dumping doors having improved trip mechanism for automatically dumping the bucket. Other objects. are n'ientioned and described herein.

The preferred embodiment of my inven tion is well illustrated in the accompanying drawing in which Figure 1 is a side clcvation of a bucket to which my invention is apphcd; Flg. 2 1s a section in elevation through the bucket shown in Fig. 1; Fig.

3 is an enlarged fragment of the bucket bottom showmg" one door and'the trip mechan1sm 1n operative position; and Fig. 4 15 a view showing the bucket operated by an overhead carrier system having a tired trip member.

Similar numerals of reference indicate similar members and parts of members throughout the several views on the drawing.

On the drawing, the numeral 1 indicates a bucket body open at the top and bottom thereof, said bottom being normally closed by a pair of cooperating dumping doors 2 and 3, respectively, which are hinged to the bucket at l and 5,, respectively. and adapted to swing downward. for dumping the bucket contents.

Numerals 6 and 7 indicate coil springs anchored within and to the bucket at 8 and 9, respectively, and at 10 and 11, respectively,

to the doors 2 and 3, said springs being adapted to maintain a closure of said doors and to effect a closure thereof after the bucket has been dumped. Numeral 12 indicates a carrier bar rigidly fastened to the under side of the door-E5 at 13, 13 and extending transversely of the bucket bottom and beneath and across the door 3, said bar being referably of channel formation opening ownward and adapted to support and carry the doors 2 and 3 when the outer end ll of said bar is discn a eabl su Jorted as hereinafter described? a 7 Numeral 15 indicates a latch or carrier lever pivotally mounted on the'bucket e3rtenor at 16 toswing in a vertical plane, said lever being provided with a ledge or abutment section 17 adapted to project beneath the carrier bar end'14 for supporting the bar 12, and therel'iy said. doors 2 and 3, said lever being providcdalso with an extension arm 18 which is outwardly pressed by the spring- 19 secured to the bucket exterior at 20 for yieldingly projecting the lower endof the lever 15 and ledge 17 inward and maintaining the latter beneath the bar end 14-. The lower end of the lever 15 is beveled at 21 for engagement by the bar end 14: when the door and. said bar are swung upward by the spring 6 to facilitate engagement of the led go 1'? by the bar end. 14-.

Numeral indicates a latch trip member carried by the bar 12, one end wherml is hinged to the lower cnd'oi" a link 23 at 24, the upper end of said link being pivotally mounted in the channeled bar 12 at 25, said hinge .ilbeing substantially spaced. beneath said bar member. lhe trip men'iber 22 is preferably of channel formation the flanges whereof are cut away at 26 adjacent the outer end lhcrcoi. thereby forming book 27 thereon, said space 26 being on- Qagotl by a carrier pin 28 fixed transversely oi and in the bar 12 :uljarcnt the bar outer end 14. Xumeral 29 indicates a spring anchorcllin the bar 152 at 30 and in the trip member '22 at 31, being adapted to retract the trip'hook 2'? against the stop pin 28 to 227 whereof norn'ially disposed adjacent 100 the latch li-rlp'il'l. .Yumeral indicates a bucket bail applied thereto in any suitable form and manner.

In operation, the descent of the loaded bucket projects the trip men'iber hinge 2; 10.5

upward by contact with the ground or a pile of material already deposited. thereby projecting the trip book 27 outward against the lower end of the latch lever 15 adjame t the ledge 17, whereby said ledge is tipped} no outward from beneath the bar on I Thereupon, the weight of the bucket dontents forces open both doors 2 and 3 and the bucket is emptied. In Fig. 4: the bucket is shown as a .con, eyer bucket supported by a movable carrier member mounted upon a carrier cable 34, upon which said carrier member is adapted to be drawn back and 1. The combination with a bucket of theclass described provided With a pair of hinged bottom dumping doors, of a carrier bar member mounted upon one of said doors and projecting therefrom beneath and across the other door; a movable spring pressed latch member engaging beneath said bar for supporting same and said doors; and a movable trip memberimounted upon said carrier bar and adapted to actuate said latch member upon the descent of the bucket, whereby said latch is disengaged from beneath said carrier bar.

2. The combination with a bucket provided with a pair of hinged bottom dumping doors, of a carrier bar member mounted upon one of said doors and projecting therefrom beneath and across the other door; a movable spring pressed latch member engaging beneath said bar ,and adapted to support same and said doors; a movable spring retracted trip member carried by one of said doors and adapted to actuate said latch member upon the descent of the bucket, whereby said latch is -discngaged from beneath said carrier bar; and'a stop member for limiting the retracted movement of the trip member.

3. In a bucket. of the class described, a hinged bottom dumping door carried by the bucket; a carrier bar mounted upon said door and extending across the bucket bottom; an oscillatory spring pressed carrier lever mounted upon the bucket and engaging beneath said carrier bar for supporting same and thereby said door; a movable spring retracted trip mcn'lbcr carried by said door and adapted to actuate said lever upon the descent of the bucket, whereby said lever is disengaged from beneath said carrier bar; and a stop member for limiting the retracted movement of the trip member.

4-. In a bucket having a hinged bottom dumping door, a carrier bar mounted upon said door and extending across the bucket bottom; a movable spring pressed bar carrier member mounted upon the bucket and provided with a ledge adapted to normally engage beneath said bar for supporting same and thereby said door; a trip supporting member mounted upon said carrier bar adjacent its outer end; a movable spring retracted trip member having one end thereof arranged adjacent said bar carrier member and carried by said trip support member, the other end thereof being otherwise carried, said trip member being adapted to actuate said bar carrier and thereby its ledge from beneath said bar upon the descent of the bucket, whereby said door is free to open; and means for limiting the retracted movement of the trip member,

5. In a bucket having a pair of h nged bottom dumping doors, a bar mounted upon one of the doors and extending therefrom beneath and across the other door; an 0scillatory spring pressed carrier lever mounted upon the bucket and engaging beneath said bar and adapted to support same and thereby said doors; a trip supporting member mounted upon said bar adjacent its outer end; a movable spring retracted trip men'iber having'one end thereof hinged to a link which is .pivoted in said bar member, the other end of said trip member being carried by said supporting member and arranged adjacent said carrier lever, said trip member being adapted to oscillate said carrier lever upon the descent of the bucket,

whereby said lever is disengaged from bencatll'said bar; and means for limiting the retracted movement of the trip member.

In. testin'iony whereof I have hereunto a1 fixed my signature this 27th day of May, 1918.
